Multiple Choice

In IV contamination, which of the following best describes the expected results?

IV contamination introduces external fluids, typically saline, into the blood sample. This adds sodium and chloride from the IV solution and dilutes the rest of the plasma. As a result, the measured concentrations of Na+ and Cl− rise due to the added ions, while potassium, total protein, and urea become diluted and therefore decrease. The pattern that matches this is an increase in Na and Cl, and decreases in K, TP, and UREA. This aligns with the correct choice.
